It also simplifies the development and manufacturing of multiple output power supplies, particularly those in pact enclosures or with high efficiency requirements. The Inno Switch3-MX architecture is revolutionary in that the devices incorporate both primary and secondary controllers, with sense elements and a safety-rated feedback mechanism into a single IC. Close ponent proximity and innovative use of the integrated munication link, Flux Link, permit accurate control of a secondaryside synchronous rectification MOSFET with Quasi-Resonant switching of primary integrated high-voltage switch to maintain high efficiency across the entire load range. This version of Inno Switch3 is intended to be used with Inno Mux for multiple output, single-stage power supplies for monitors and TVs. This enables very high system efficiency on a small PCB foot print. VLED VOUT2 D Inno Switch3-MX Primary FET and Controller V BPP Secondary Control IC Figure 1. Typical Application/Performance.
